The image displays seven upright rectangular cards labeled 1 through 7, positioned in a symmetric, ascending-then-descending staircase formation: cards 1-4 rise left-to-right, then 5-7 descend. Each card is outlined in black with centered numerals, set against a plain white background for maximum clarity. This minimalist design emphasizes numerical progression and spatial balance.
